Hey Sonos,
I have followed many threads on this topic. The default volume by source I understand is not feasible with so many variables. Let’s simply start with a default “start up” volume. No matter the source it’s reasonable to assume that most handle more volume at night than in the morning. Every morning I sit down with coffee, ask SVC to play something morningish and get blasted until I ask SVC to turn it down. Please give us the option when we fire our system up to turn the volume up not down if needed.
